B1615-PANEL ILLUMINATION CONTROL CIRCUIT OPEN





For a complete wiring diagram, refer to the Wiring Information Electrical Diagrams.

- When Monitored:
With the ignition on.

- Set Condition:
The Instrument Cluster detects an all open condition on the Panel Illumination Control circuits.





Theory of Operation

The Panel Illumination Control Circuits share a common 12 volt driver from the Instrument Cluster. In order for this DTC to be set, ALL Panel Illumination circuits must be open.

1. TEST FOR AN INTERMITTENT CONDITION
1. Turn the ignition on.
2. With the scan tool, record and erase DTCs.
3. Turn the ignition off, wait 10 seconds then turn the ignition on.
4. Turn the headlamps on.
5. With the scan tool, read DTCs.

Does the scan tool display: B1615-PANEL ILLUMINATION CONTROL CIRCUIT OPEN?

Yes

- Go To 2

No

- The condition that caused this code to set is not present at this time. Using the wiring diagram as a guide, inspect the wiring and connectors for an intermittent condition. Operate the system several times and recheck for active DTCs.
- Perform the BODY VERIFICATION TEST Body Verification Test.

2. CHECK CONDITION OF THE WIRING AND CONNECTORS ASSOCIATED WITH THE PANEL ILLUMINATION OUTPUT CIRCUITS




1. Turn the ignition off.
2. Disconnect the Instrument Cluster C1 harness connector and inspect the connector and associated wiring for the Panel Illumination System.
3. Using a fused jumper wire, probe cavity 7, 19, and 20 of the Instrument Cluster C1 connector.

Did the components illuminate?

Yes

- Replace the Instrument Cluster.
- Perform the BODY VERIFICATION TEST Body Verification Test.

No

- Repair the faulty wire(s)/connector(s).
- Perform the BODY VERIFICATION TEST Body Verification Test.
